JELLY CAKE "Oranges in yogurt"

Pour gelatin orange juice and leave it to swell.
Oranges cut into slices and remove their peel.
Cubes slice the bananas and biscuit.
When gelatin is swollen, put it on the fire until it is completely dissolved (but do not boil). Cool and add the yogurt.
To prepare a semi-circular bowl and covered it with plastic wrap, and then put back mugs cooked oranges (on the walls), a small portion of banana and biscotti, mugs of orange, and so a few layers, then pour all the yogurt and refrigerate.
When the jelly cake hardens, remove it from the mold and garnish with berries and mint.
